Twittmail transfers only tweets of the users you can’t miss reading to your mobile phone or PC e-mail address and reliably delivers your important information that tends to be buried in noise.

When you register keywords related to things you care about, people's names, twitter user names, and so forth, tweets that include the registered words are put together and delivered by email.
For the delivery time you can choose between two deliveries, morning and evening, or a morning only delivery.

At each set delivery time 20 of the newest tweets are sent.
There are 9 ways that you can set: every 24 hours, 12 hours, 6 hour, 2 hours, an hour, 45 minute, 30 minutes, 15 minute, and real-time.

Twittmail was created in order to be able to pleasantly use Twitter on mobile phones.
Twittmail website for mobile (http://m.twittmail.jp/) can be used as a Twitter client for mobile phones that allows for comfortable time-line browsing, not only delivery time setting, designation of target users, and specification of keywords.
